Techniques for automatically prompting a calling user to send a message to a called user, the calling user using a calling device and the called user using a called device, the method including receiving, at a processor in the calling device, an indication that a call from the calling device to the called device has disconnected, determining, at the processor in the calling device, whether the call connected before receiving the indication that the call has disconnected, and in response to determining that the call did not connect before receiving the indication that the call has disconnected, determining that the call was a missed call.

Provided herein is a holistic fraud cocoon that protects a user from incoming or outgoing fraud and phishing communications by capturing, analyzing and either altering, discarding or presenting communications to the user. For example, the holistic fraud cocoon captures all incoming sources (mail, in-person visits, phone, TV, radio, newspapers and internet) and the actions performed by the user, triggered by those sources. Certain actions are held in a queue to be reviewed, validated and acted upon by a third party before the actions are executed.

In an information processing system, a storage unit stores data related to a voice of a user for each item of user identification information that identifies the user during transmission or reception of a call. An acquisition unit acquires the user identification information on a calling side and data related to the voice of the user on the calling side after a call is started. A determination unit determines whether the data related to the voice of the user on the calling side and the data related to the voice stored by the storage unit in the user identification information acquired by the acquisition unit are based on the voice of the same person during the call.

A computing device may receive, from a remote computing device, a request to establish a communication session with the remote computing device and contextual information indicative of an urgency level of the communication session. The computing device may output, at one or more output devices, the contextual information indicative of the urgency level of the communication session and at least one of: haptic output or an audible alert that indicates the request to establish the communication session.

Provided is a method of visually displaying a countdown time on a graphical user interface. A countdown time is set, the width and opacity of an area that changes as the set time is sequentially counted down are determined, and the area that changes based on the determined width and opacity is output on the graphical user interface.

Provided is an operation method for a terminal performing a call. A first terminal may receive a first like signal transmitted from a second terminal to a server, and may transmit, to the server, a second like signal regarding a second user of the second terminal. At this time, the first terminal may receive a signal for establishing a call connection between the first terminal and the second terminal, and may perform a call with the second terminal based on the signal.
